Here is the approach I used:
1. How much do they spend on running the service each year? ~£180M
2. How many people did they save? 389
3 How many of these were illegals crossing the channel? 108
4 what is the average cost per life saved. (389 / £180m) £463k
5 Using the per life saved model we have a cost of £50m but that is way too simplistic.
6 Why don't we accept the per launch argument that it's just 3%? 9,312 launches £19,330 avg giving a figure of £5.6M? Not all launches cost the same. 56% of launches are for the lowest cost craft, B & D class and launches includes all training, patrols, sea trials etc. The B & D cost 1/10th and 1/20th of the cost of the all weather craft.
If we look at the all weather class boats stationed in the SE, we have a 146 saves of which 108 were illegals. Thats close to 74% and accounts for at least 20% off their costs even allowing a generous cost allocation to the B & Ds which are noise in the numbers.
7 Costs have increased £30M from 2021.
The 3% claim is therefore nonsense, designed to distract attention away from divisive activity, which is costing them donations.
you must be unaware that a successful claimant can extend the invite to his or her family lawfully.
